Specification of Letters Patent.

' Patented March.2,'- 1909.

Application med April 15, 1908. Serial No. 427,239.

To all whom it may concern:

Be it known that 1, PAUL O. PoULsoN, a citizen of the United States, and a resident of Brigham, in the county of Boxelder and State of Utah, have invented a new and improved Explosion-Turbine, of which the following is a full, clear, and exact description.

This invention relates to turbines and gas engines, and the object of the invention is to produce a turbine which will be propelled by exploding charges within the same. The general purpose is to produce a prime mover of this class which will be efficient in operation and extremely simple in construction.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a longitudinal vertical section taken through an explosion turbine constructed according to my invention; Fig. 2 is a vertical cross section taken through the engine on the line 2 2 of Fig. 1; and Fig. 3 is an end elevation of the engine showing the upper portion thereof as viewed from the left of Fig. 1.

Referring more particularly to the parts, 1 represents the main frame of the engine, and 2, 2 represent pedestal bearings for the shaft 3 of the engine. To the end of this shaft there is attached a rotor or wheel 4 which has an enlarged hub 5 connected by a disk body 6 with a rim 7. On the inner side of this rim 7 a plurality of buckets 8 are formed as indicated most clearly in Fig. 2. These buckets are slightly curved rearwardly with respect to the direction in which the rotor rotates. At the rim 7 an inwardly projecting flange 9 is formed on the side thereof opposite to the disk body 6, and this flange is provided with a plurality of exhaust openings 10 disposed respectively between the buckets 8 as indicated. In the disk body 6 I provide a plurality of openings 11 which communicate with the atmosphere, and these openings are covered by hoods 12 which are adapted to catch the air and draw the same into the body of the rotor as it rotates.

Within the rotor 4 there is provided a rigid stator 13, the construction of which is clearly shown in Fig. 2; it has the outline of a drum having a slightly smaller diameter than the internal diameter of the rotor, from which arrangement the inner edges of the buckets 8 lie close to the face of the stator, as indicated in Fig. 2. Although this stator presents the outline of a drum, its body is cut away as indicated in Fig. 2, so as to form an explosion chamber 14. The side walls of this explosion chamber are curved as indicated at 15 and 16, so as to act as guides tending to direct the gases of combustion in the direction in which the rotor rotates. In this way two oppositely disposed abutments 17 are formed having enlarged ends 18 and reduced or tapered ends 19. Between the enlarged end of one abutment and the small end of the opposite abutment, guide vanes 20 are provided, which are curved, as shown, in the direction in which the rotor rotates. These abutments 17 and guide vanes 20 extend continuously across the rotor, connecting the side plates 21 thereof, as shown. This stator is rigidly supported upon brackets 22, which are supported upon a frame plate 23 which sur-- mounts t e main frame 1, as shown in Fig. 3.

On the interior of the rotor and on the side face thereof which is disposed adjacent to the main frame 1, an i niting pan or plate 24 is attached. This p ate has a shallow dished body, as indicated in Fi 2, the outer end whereof is turned vertica ly to form a wing 25. The outer side wall of the stator opposite to this .wing 25 is rovided with an injector opening 26, and t is opening is in alinement with a duct 27 which is formed in .the end of a feed chest 28. This feed chest has a horizontal barrel or cylinder 29 formed therein, in which a plun er or piston 30 reciprooates. The forwar part of the barrel or cylinder 29 is provided with an upwardly extending port 31 which communicates with a valve chest 32 in which valve chest there is guided a slide valve33 having a vertically disposed feed opening 34 therethrough, as shown. Above the valve chest 32 an inlet connection 35 is provided through which gasolene is drawn in. This inlet connection 35 communicates with a bonnet 36 having a vertical bore in which a governor plunger 37 operates. On the bonnet 36 there is seated a governor 38, the stem 39 of which is adapted to be raised and lowered in the usual manner by means of governor weights 40 which fly outwardly as the speed of the engine increases. In thisway the stem 39 may move the plunger 37 downwardly so as to partially or comp etely obstruct the inlet opening 35.

I vide with a cam groove '42. cam

groove operates a lever 43 mountedupon a racket at 44, and the lower end .of this lever In this way the engine governs itself automatically. Near the igmting pan 24 a s ark plug 41 is provided. The plunger an the arts cooperating therewith constitute an injector for. forc' the charges of gasolene into the interior 0 the-stator. Y

In order to operate the 'valve 33 and the plum r 30 automatically, the hub 5 is -prooperates a slide rod 45 which passes longitudmally of the engine near the base plate 46 thereof. The end'of this slide rod 45 attached to an arm 47 ofa segment 48, this segment meshes with 'a' segment;4 9

which is with a plunger arm 50. This '24 there is provided an air valve'56 which opens'inwardly so as to admit atmospheric air at the proper time into the interior of the stator. It is mechanically operated by a link 56 from the lever 53.-

The governor 38 is driven by a horizontal governor shaft 57 running parallel with the main shaft 3, and driventherefrom by a suitable belt 58, as shown. The shaft 3 is provided with asuitable belt pulley 59 for riving machinery from the engine.

The outer face of the flange 9 is substantially covered by exhaust rings 60, but the upper and lower ends of these rings are separated so as to form gaps, as indicated at 61 and 62, and when the exhaust ports 10 are passing these gaps exhaust takes place.

In order to center the rotor accurately on the stator, the end of the shaft 3 is formed with a tapered projectin nose 63 which extends into the interior 0 the rotor, and the adjacent face of the rotor is formed with a small counterbore 64, which receives this nose and centers the stator, as will be readily understood.

The mode of operation of the engine will now be described: As the rotor rotates, the cam groove 42 rocks the cam lever 43 and reciprocates the slide rod 45. In this way. the valve33 and thelunger 30 will be reci rocated in opposite 'rections the travel 0 the valve 33 is sufiicient to bring; the port 34 thereof under the bonnet 36, so that a charge lhaust of gasolene into the valve. the valve is at the limit of its forward movement, as indicated in Fig. 1i this charge may pass down the 31 into o'rward end of the barrel or re 29. Then, with the forward movement of the plunger 30 this charge is through the duct 27 inttethe interior stator, wmg' 25 so astobetransformedinto a ray. Itwill benoted thatthe "H; 255! v-IHHI stantially at right to the path of the charge 'of fuel as it is projected violently into the explosionchamber by the injector. The

high temperature the explosion cham-- ber of the stator and the air which is an plied through the valve 56, forms an expl d sive mixture which is ignited by the electric s at the sparking plug 41'. 7 explosion takes place the gases of cemhiistion i which are at a high pressure, tend to'findiexit from the explosion chamber. In flowing out,'they. are directed by the faces 15 and the vanes 20, the direction in which-the rim oftherotor moves. In this wayi tliey their energy upon the inner 'faces -of-the buckets 8 and'rotate the rotor.

; buckets 8 as the open exhaust ports at pet and ower side of the engine, ex-

If the engine should tend .tii run 3st, thegudrgernor will rlillolye thhe p.e1;37 ownw soastoco'ete su i of fuel.

e I have intended this turbine to be used especially as an explosion turbine, the rotor and stator may be used as a steam turbine by admitting steam to the interior of the cated. The interior of the stator will then constitute a steam space from which the steam flows outwardly against the buckets 8 in such a way as to cause the rotor to rotate.
